TRANSITION CAR-COUPLING.

To all whom it may concern:

Be it known that I, WILLIAM Kunsma citizen of the United States, 'residmg at declare the following to be a full, clear, and

exact (description of the invention, such as i will enable others skilled in the art to which i it appertains to make and use the same.

My invention relates to the construction of transition car couplings enabling cars pean hook type or to cars havingcouplers of the, Master. Car Builders type, as well as to cars equipped with similar transition p MpC. B.'coupler having a head 1, a knuckle couplings. .During the period when couplings of the hook type are being gradually supplanted by couplers of the M. C. B.-type, a form of transition coupling that w1ll'couple with both; of the other types must be employed, andyfor obvious reasons of economy, it is desirable that such transition couplings shallbe of a character rendering them readily convertible into typical M. C. B'. couplers after the necessity for transition couplings is past.

.The principal readilvassembled and disassembled. A further object ofthe invention is to so combine.

the M. G B. coupler 'mechanism and the auxiliary. coupling devices for cooperating. with the hook coupling of the European "type that pulling strains communicated to the M. C. B. coupler elements from the auxiliar'y coupling devices may be distributed and equalized so as to maintain a central or substantially central draft upon the M. C.

B; coupler.

horizontally rotatable link which is adapted to be connected :to a hook coupling of the European type, the equalizer'bar being dea tachably interlocked to the means for con Specification of Letters Patent.

the drawings illustrating the preferred,

form in which I have contemplated apply ingethe principle of my invention, the scope whereofis pointed out in the claims,

.Figure 1 is a plan view of a transition car couplingembodying the invention.

Fig. 2 -is a side, elevation of the mecha f nism shown m Fig; 1., the auxiliary coupling device being in coupling position.

F g.3 is a view in side elevation, illustrating the position to which the parts are broug t :when effecting the dissociation of the auxiliary coupling device from the M. C. B. coupler mechanlsm.

Fig. 4 is a detail front elevation of the equalizer bar of the auxiliary coupling de The transition car coupling involves an with another coupler of the same type. A

well known form of M. C. B. coupler is illus trated 1n the drawings; but, except as hereinafter claimed in particular combinations of parts the details of construction of the elements constituting the M. C. B. mechanism may be of any suitable, or ordinary object of the invention is to provide a conveniently manipulated and v eflicient transition coupling which-may be construction. As a means for movably connecting to the coupler head 1 the coupling device by which the car may be coupled to another car equ pped only with a coupling of the European type, the coupler head is preferably formed withjoppositely disposed laterally pro]ect1ng hooks 4:. whose bights open toward the rear. The hooks 4 respectively extend through corresponding eyes 5 formed at the rear ends of link members 6 which are movably connected at their forward ends tothe outer ends of a transverselyex- I I tending equalizer bar 7. For the purpose Generallv stated, these objects are 'accomplished by movably securing to the head of an M. C. B. coupler'a transversely extend- .ing equalizer bar bearing at its center a of forming a connection with the equalizer barthelink members 6 are preferably pro-.

vided attheir "forward ends with eyes 8,

similar to the eyes 5, and the equalizer bar with a hook coupling of the European type the hooks 4 and .9 face in opposite direcbecoming accidentally disassembled; but,

as will be readilyunderstood upon refertionS, thereby preventing the device from Y V provision being thereby made for free pivence to Fig. 3 of the drawings, the parts nevertheless may be readily detached from each other forthe purpose of repairing or renewing Worn or damaged members by simply swinging the equalizer bar 7 upwardly and rearwardly until the hooks in and 9 are parallel. In this relation ofthe books the link members 6 may be rotated on their longitudinal axes and disconnected.

The transversely extending equalizer bar 7, which in coupling position stands in advance of the knuckle 2 of the coupler bears consonance with the movements of the opposed buffers on the connected cars. To permit extended rearward sliding of the link" 10 the outer end of the knuckle 2 is formed with a centrally disposed horizontal slot 13- adapted to receive the rear end of the link. As shown in Figs; 1 and 4t thes'lo't 11 in the equalizer bar is preferably flared forwardly, and as illustrated in dotted lines in Fig. 1' the wall of the knuckle at the base of the slot 13: preferably slepes from the rear forwardlyaway from the longitudinal axis of the coupler head 1,

I Whennot in use for coupling cars to: g'e'tlier the" auxiliary" coupling devices by when connection with a hook ceupling is efi'ected 'hang vertically from the hooks 4 under all usual on the" sides or the coupler head. In this' position the" auxiliary hook coupling devices do not interfere with the use of the MT. 6'. B. coupler mechanism.
